          Abstract

          ABSTRACT Purpose: to analyze the absolute latencies of waves I. III and V and the interpeak intervals I-III. III-V and I-V of the ABR recorded from different age groups of children with congenital zika virus infection and their peers without risk indicators for hearing impairment. Methods: 84 newborns and infants (N=51 study group and N=33 control group) divided into groups with different post-conceptual ages. with the results of their hearing exams analyzed by age group and compared with their peers without other risk indicators for hearing impairment. The assessment of the auditory pathway was conducted through tympanometry. otoacoustic emissions and auditory brain stem responses. Results: only the latency of wave I and the interpeak III-V showed no significant difference between the study and control groups. The absolute latency and interpeak values found in the study group were significantly lower than those found in the control group. Conclusion: the maturation of the brain stem in children with ZIKV infection occurred within normal limits. with no retrocochlear disorders until the age of 5 years.

          RESUMO Objetivo: analisar as latências absolutas das ondas I. III e V e os intervalos interpicos I-III. III-V e I-V do Potencial Evocado Auditivo de Tronco Encefálico obtidos em diversos grupos etários de crianças portadoras de infecção congênita por zika vírus e nos seus pares sem indicadores de risco para deficiência auditiva. Métodos: foram recrutados 84 recém-nascidos e lactentes (N=51 grupo de estudo e N=33 grupo controle) separados por grupos com diferentes idades pós-conceptuais. sendo os resultados dos seus exames auditivos analisados por faixa etária e comparados com seus pares sem outros indicadores de risco para deficiência auditiva. A avaliação da via auditiva foi realizada por meio da timpanometria. emissões otoacústicas transientes e potencial evocado de tronco encefálico. Resultados: somente a latência da onda I e o intervalo interpico III-V não apresentaram diferença significante entre grupo de estudo e controle. Os valores de latências absolutas e interpicos encontrados no grupo de estudo foram menores do que os obtidos no grupo controle de forma significativa. Conclusão: a maturação do tronco encefálico nas crianças portadoras de infecção por Zika Vírus ocorreu dentro da normalidade. não apresentando alterações retrococleares até a idade de 5 anos.

          Language of early- and later-identified children with hearing loss.

          To compare the language abilities of earlier- and later-identified deaf and hard-of-hearing children. We compared the receptive and expressive language abilities of 72 deaf or hard-of-hearing children whose hearing losses were identified by 6 months of age with 78 children whose hearing losses were identified after the age of 6 months. All of the children received early intervention services within an average of 2 months after identification. The participants' receptive and expressive language abilities were measured using the Minnesota Child Development Inventory. Children whose hearing losses were identified by 6 months of age demonstrated significantly better language scores than children identified after 6 months of age. For children with normal cognitive abilities, this language advantage was found across all test ages, communication modes, degrees of hearing loss, and socioeconomic strata. It also was independent of gender, minority status, and the presence or absence of additional disabilities. Significantly better language development was associated with early identification of hearing loss and early intervention. There was no significant difference between the earlier- and later-identified groups on several variables frequently associated with language ability in deaf and hard-of-hearing children. Thus, the variable on which the two groups differed (age of identification and intervention) must be considered a potential explanation for the language advantage documented in the earlier-identified group.

              The newborn with hearing loss: detection in the nursery.

              Early detection of hearing loss coupled with appropriate early intervention is critical to speech, language, and cognitive development. These competencies serve as the foundation for later academic skills. For these reasons, many states are undertaking aggressive efforts to screen all newborns before hospital discharge. Universal detection of hearing loss in newborns is a three-stage process composed of 1) the birth admission screen, 2) follow-up and diagnosis, and 3) intervention services. Breakdown at any stage jeopardizes the entire effort. The goals of this research are to examine the birth admission screen by reviewing outcome measurements for 54 228 Texas newborns and to evaluate factors that impact outcomes positively or negatively. All newborns were screened for hearing loss using a physiologic test of auditory function; either screening auditory brainstem responses or transient evoked otoacoustic emissions. Screening occurred in the newborn and intensive care nurseries, before hospital discharge in 9 sites as part of the nursery protocol. Patients. A total of 54 228 newborns were available for screening. Four measures were evaluated and are reported: the number of births screened, the number of newborns who passed the screen before discharge, the number of infants who returned for follow-up, and the number of infants identified with hearing loss. A Birth Screening Performance Index is also calculated. Results are reported for calendar years 1994, 1995, 1996, and through June 1997. A total of 54 228 newborns were available for screening; 52 508 were screened before hospital discharge during their birth admission and 50 721 passed this screen. Infants returning for follow-up screen as outpatients numbered 1224. Over this 31/2-year span, 113 infants who failed the birth admission screening had hearing loss that was sensorineural in nature. From these data, the estimated incidence of hearing loss is 3.14/1000 infants. Screening in the nursery with low false-positive rates can be achieved when three elements are present: audiology involvement, hospital support, and automated data and information management. Follow-up measures need improvement. Better tracking methods may help assure that at-risk newborns are connected to services.
